Anterior segment changes following Nd: YAG laser posterior capsulotomy: a quantitative ultrasound biomicroscopy study.
Article in Lasers in medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo evaluate the effects of neodymium-doped yttrium-aluminum-garnet (Nd: YAG) laser posterior capsulotomy on anterior segment parameters in pseudophakic eyes using ultrasound biomicroscopy (UBM).
methodsThis prospective study included 35 pseudophakic eyes of 34 patients with visually significant posterior capsule opacification (PCO) following uncomplicated phacoemulsification with a one-piece hydrophobic acrylic intraocular lens. UBM was used to assess anterior segment parameters, including anterior chamber angle (ACA), anterior chamber depth (ACD), anterior chamber width (ACW), lens vault (LV), and iris thickness (IT). The angle opening distances (AOD) at 500 μm (AOD500), and at 750 μm (AOD750), the angle recess area (ARA) at 500 μm (ARA 500), the trabecular-iris space area at 500 μm (TISA 500), and at 750 μm (TISA 750) were measured both temporal and nasal area. The measurements were taken three times, the first time before the Nd: YAG capsulotomy, the second time 1 week after and the third time 1 month after the procedure.
resultsNo statistically significant changes were found in intraocular pressure (IOP), central corneal thickness, ACD, ACW, LV, or IT following capsulotomy. However, a significant and sustained increase was observed in angle-related parameters (ACA, AOD500/750, ARA500, and TISA500/750) at both 1 week and 1 month post-procedure(p < 0.05 for all). No significant changes were detected between the 1st week and 1st month measurements of angle-related parameters (p > 0.05 for all).
conclusionNd: YAG laser capsulotomy leads to significant widening of anterior chamber angle structures without affecting IOP or ACD. These findings suggest that the procedure is safe and may positively influence aqueous humor dynamics.
